I need to connect up to sixteen phones per building, I can use a cheap hub, but POE would be useful. Is there a cheap POE hub available? Everything I have seen has been expensive. Chris Mason

I am hoping that someone has had better luck with this than I have. I would like to connect Cisco 7940s and 7960s to the Netgear FS116P, and take advantage of its POE. I know that the Cisco phones use Cisco's "pre-standard" POE implementation, but as I understand it the difference is really only two pins. I bought a bunch of PowerDsine inline power adapters which supposedly change

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Are any versions of the Cisco 7940/7960 or 7940G/7960G phones compatible with the 802.4af Power over Ethernet Standard? Ok, I know the question has been asked before, but googling has turned up several contradictory results: 1/ No - not at all 2/ Maybe - 79XXG will work 3/ With a special cable/dongle (a la wikki) I am looking at getting

As an alternative to the "expensive" PoE switches out there, I found the D-Link Web Smart DES-1316 switch for just around $400. Now, the issue is, it does 802.3af power and, as I've found out through previous discussions, this original 76?0 series phones (the non G variety) do not use 802.3af. So I'm assuming I just need to use the special cable thing as per

I know this is on the wiki, I just want to confirm so I don't blow up my cisco phones. I've got several cisco 7940's all running using cisco power cubes. However, my boss wants me to switch just a few over to poe, but doesn't want to fork out the dough for a nice cisco poe switch, or anybody else's poe switch for that matter. So my question is, what is the '99.999%

I'm looking for 24 or 48 port IEEE802.3af POE injector. Any recommendation? -------------- next part -------------- An HTML attachment was scrubbed... URL: http://lists.digium.com/pipermail/asterisk-users/attachments/20070720/3886655b/attachment.htm

I'm having problem powering Cisco phone's (7940 and 7905) on Linksys SRW224P switch (with PoE functionality). I have tested three phone's, one is working (7905) and two aren't (7905 and 7940). I have plugged all three phones on same switch port with same cable! Do I need to change anything in phone configuration? Is there something wrong with Linksys switch? How can I troubleshoot

Ok, not exactly an Asterisk problem, but... I picked up some SNOM 200 phones because SNOM's have been recommended for use with Asterisk and they have line buttons that can subscribe to presence. However, they don't appear to power up when connected to my Negear FS108P, which is an 802.3af Power-over-ethernet capable hub. I am pretty sure these are the SNOM 200b, in that the ethernet

Based on several threads I've read on this list, I assume that it would be handy to supply POE (power over ethernet) in an environment without having to purchase POE switches (assumed expensive) and abandon one's existing (familiar/custom/not-yet-expensed/etc.) switches/hubs. Assume I have a non-POE switch with 24 RJ-45 (ethernet) ports. I design a 1U box that can be mounted just

Is anyone using a 3com 3CNJPSE to power a 7960G? I have a couple of 7960Gs and 3CNJPSEs but no combination appears to work. Both phones work fine with a cisco power cube. I get a 47.6V reading across pins 5 and 8 on the patch cable coming from the 3CNJPSE. The network still works through the 3CNJPSE, just no power to the phone until I connect the power cube. Using two straight through wired

Hi, I'm not clear on how to use Power--over-Ethernet, specifically with Polycom phones. What I understand, is that by buying the Polycom 501 with the 802.3af cable bundle, I simply connect my phone, through the Polycom provided "special" RJ-45 cable, into a PoE capable switch, and voil?! Is this true? And if so, what happens when the Phone doesn't connect directly to the

Hi listers, I am looking for people who have used Power over Ethernet switches, primarily in conjunction with Polycom IP 501's. I've been looking at the Linksys SRW224P, since I've had good luck with the SRW224 in our office. However, Nortel, Cisco, Adtran, etc. all have an offering, all of which vary in price. I would appreciate any input people have to offer. Thanks, James

I -think- that the Sipura 841 was PoE... and I'd been anxious to find out. However, according to Atacomm.com, it's been delayed until mid-January. *sigh* So: does anyone know of a (decent) phone that meets the following criteria, and isn't too expensive? - SIP - two (or more) lines - some form of TCP/IP-based configuration - 802.3af (power-over-ethernet) - 100 Mbit passthrough (not

I'm trying to spec out hardware for a new office, and I'd like to include power over Ethernet as an option. I've seen a handful of PoE injectors around $1000 for 24 ports and a couple switches up around $2500 for 24 ports. Are there any cheaper options, short of buying a boatload of 1-port injectors off of ebay? I don't really need more then 24 ports of PoE out of 48 total

Hi, Do you need a special cable and power for that unit or you can run it of PoE Switch? Thanks. robert

When I bought two Polycom 501 SIP phones, I naively thought they were Power-over-Ethernet (IEEE 802.3af) because they were "powered over ethernet." Silly me. Polycom must have some odd voltage or funny way of injecting the power, because the POE switch I bought for them (Netgear F@510P) won't power them, though if I use the Polycom-supplied AC adapter and ethernet power

Sorry for posting slightly off topic, I use an Avaya 1152a1x midspan device to deliver power some Snom phones. The Power distrubution unit seems to be identical to PowerDsine PD-6024G/AC/M. I can get some basic information via SNTP (networking setup, uptime) but no port monitoring and no monitoring of power output using snmpwalk on the device. Does anyone has experience wit such an device?

Hi all, For a top quality setup, I will need to install high quality VoIP switches with QoS and PoE. My potential customer should not have any problem with call quality. Experienced folks, Please advice me what switches to install and at what price. I may need it for upto 100 phones. What else should I consider so that phones work without problem along with the computers on the same network?

We are currently considering the Linksys POE switch for a small Asterisk office deployment. There will be no separate wiring closet to put it in. Can anybody tell me if this switch has a loud fan? Users would not be able to tolerate a loud noise close by. Otherwise we will go with a fanless desktop switch. Thanks, -- Andres

Shawn, That's a complete load of manure. I have an office full of 7960's, they work great with asterisk with the SIP images loaded. I'm about to pick up a lot of 7912's (simple one line phones, same as the 7905 but it has a built in switch). These phones have also been confirmed to work with Asterisk. I would recommend not going directly to cisco, and just find a reseller who
